Nitrogen is sp2 hybridized. The molecule has a bent geometry with an ONO bond angle of approximately 120°. (b)
Nitrogen is sp2 hybridized. The molecule has a bent geometry with an ONO bond angle slightly less than 120°. (c)
Nitrogen is sp hybridized. The molecule has a linear geometry with an ONO bond angle of 180°.
65. Nitrogen cannot form a NF5 molecule because it does not have d orbitals to bond with the additional two fluorine
